Zosimus, New History 1.65

Zosimus (Greek Ζώσιμος): Early Byzantine, pagan author of a history of the Roman Empire, published in the first quarter of the sixth century CE.

The translation of ZosimusNew History offered here was printed in 1814 by W. Green and T. Chaplin in London, and was probably prepared by J. Davis of the Military Chronicle and Military Classics Office. The translator is anonymous. The text was found at Tertullian.org. The notes were added by Jona Lendering.

[1.65.1] Probus, having thus gained the empire, marched forward, and performed a very commendable action for the public good, as a prelude to what he should afterwards do. For he resolved to punish those who had murdered Aurelian, and conspired against Tacitus. Though for fear of an insurrection he did not openly execute his design, but planted a company of men, in whom he had confidence, at a convenient post, near to which he invited the murderers to a feast. 

[1.65.2] Coming there in expectation of being entertained at the emperor's table, Probus ascended into a balcony from whence he could view the action, which he gave a signal to his men to perform. As soon as they had received it, they fell on the murderers in their defenseless state, and left only one of them alive, whom he caused afterwards to be burnt alive, as a very dangerous criminal.
